Overload protection: 250V DC or AC peak values

XV. Frequency (Hz)

1.

Trigger “AC/DC/EF”, and at this time it is at the AC/DC voltage automatic identification mode, and trigger
“Hz” button to choose frequency measurement.

2.

Respectively put the testlead into “VΩHz”and“COM”.

3.

Have the testing end of the testlead connected in parallel with the signal source to be measured and read the

results from the display.

Caution:

a

）

Do not input signals higher than 60V, otherwise it may damage the

instrument and bring dangers to human safety.

b

）

After all the measurements are completed, it is necessary to

disconnect the testlead and the tested circuit.
